Rook

Rook has two especially clear English associations: a dark-plumaged bird in the crow family and the chess piece traditionally shaped like a tower. The two words have different histories. The chess term came through languages including Persian, where its earlier form referred to a chariot, while the bird name belongs to the older English animal vocabulary.

As a first name, Rook lets a family choose which connection matters most. A love of birds gives it a nature story; a connection with chess supplies a different personal reference. The same four-letter spelling can hold both images without requiring them to share one origin. Its compact sound makes the distinction in meaning a larger part of the choice than the length.
